Founded in 1948 by World War II veteran Bob Trulaske, True refrigeration got its start creating bottle coolers out of downtown St. Louis warehouse, but the brand has grown into one of the largest players in the global commercial refrigeration market. Known for reliable and sanitary commercial refrigerators, the family-owned business primarily creates refrigerators out of its O'Fallon, Mo., headquarters.

True Refrigeration GDM-12-HC~TSL01 Description
The True GDM-12-HC~TSL01 one-section glass door merchandiser has a white aluminum interior that brightens the cabinet. The stainless steel floor has a built-in drain that facilitates cleaning the interior. Foamed-in-place polyurethane insulation in the cabinet helps cold air stay inside and gives structure. The black powder-coated, heavy-duty steel frame rail is corrosion resistant and has leg levelers for uneven floor installation. A black powder-coated exterior hides dents and scratches well and resists peeling and chipping.
Since the evaporator is coated with epoxy, it resists corrosion, and the bottom-mounted condenser placement provides convenient cleaning and maintenance access. The electronically commutated evaporator and condenser fan motors produce a consistent volume of air, so it produces little heat and helps save energy.
The reverse condensing fan motor helps to keep the condensing coil clean. Upon start up of the compressor, the fan blows in reverse for 20 seconds to rid the coil of dirt and debris. Although this is a self-cleaning feature, routine preventative maintenance should still be implemented to extend the unit's lifespan.
The refrigeration system keeps temperatures between 33 and 38 degrees Fahrenheit, and the self-contained capillary tube system uses environmentally friendly R290 hydrocarbon refrigerant. The True GDM-12-HC~TSL01 one-section glass door merchandiser works great in convenience stores, gas stations, and other stop-and-shop establishments.
